Generation of high-quality tunable-duration pulses by two-cell SBS phase-conjugating mirror

摘要

The pulse compression of two-cell SBS system in CCl$-4$/ liquid was experimentally investigated. The duration of Stokes pulse was tunable by simply changing the separation between two cells and the tuning range depended on the pump energy. By increasing the input energy, the wider tuning range of pulsewidth could be achieved. The near-diffraction limited output pulses have achieved and the shot to shot stability on far-field divergence angle was also measured. The numerical simulation on pulse shape of two-cell SBS system was made and agreed with the experimental results well.
